Today I received a used Brain-built MS1V3 from a forum member here. Somewhere along the line, one of the previous owners of the unit absolutely mangled the 64-pin connector side of the harness. Everything appears to be connected, they are just poorly soldered and the joints are exposed. I have purchased a new 64-pin connector and I am now in the process of soldering everything to the new connector and confirming a few things.
First off, the DB37 connector appears to be untouched and looks exactly like the DB37 from Braineack's DIY thread:
The first thing that concerns me is the ground wires on the 64-pin connector. The previous owner has one thick black wire connected to 2C and another thick black wire connected to 2A. 2D and 2B were left untouched. (Note that one of the black wires is connected to pins 7,8,9 and the other is connected to pins 17,18,19 on the DB37 connector, just like in the picture above.) Is this something I need to fix? According to Braineack's DIY thread, one wire should be split between 2C,2D and the other split between 2A,2B:
Second, on my 64-pin connector, the wires connected to 1G and 1H are opposite of the picture above. I have a brown wire going into 1G and a GRN/WHT wire going into 1H. Is this something that was done to some of the units, or did the previous owner just mess up when soldering everything back to the connector?
Any input would be greatly appreciated!
